Witryna20 wrz 2024 · The arrangement of molecules within the cell membrane makes it semi-permeable. That is, the cell membrane allows some substances to easily diffuse into and out of the cell, but it prevents the diffusion of other substances. Plant and animal cell diagram The cell wall is a rigid structure that surrounds plant cells. WitrynaThe cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.
WitrynaThe cell-wall of gram-positive bacteria, which is simply structured, is therefore more permeable to a series of antibiotics than is the gram-negative cell-wall which is built like other biological membranes. The energy dependent uptake of many antimetabolic antibiotics in managed by the selective transport systems of the cytoplasmic membrane.
